Question type: Maintenance & Repair

I'm having the same problem on my 04 silverado, but I'm also running straight exhaust and I can't give mine any gas without it misfiring like a mother f***** and then dying if I hold the gas. If I press the gas it just stutters and stalls. I'm getting the low voltage on my mass air flow and 02 sensors. Brand new stuff all the way around and still having the same problem. Unplugged my mass air flow and 02 sensors and truck still does same thing. It idles fine. I don't know how to check for vaccum leaks. A you help would be great

Sometimes when I get in my truck it starts fine and then as soon as I step on the gas it misses and backfires. I am pretty sure I have an exhaust leak on the passenger side that I need to get fixed. ...
